i My invention refers to self-discharging with'another cog wheel 10 on the end of shaft wagons and more especially to cars having 4, which projects through the end wall adoscillatable side walls and a movable bottom. joining shaft 7 By means of a crank v11 It is an object of my invention to provide a fixed to shaft 7 the wheels 9, 10 and shaft 4 5 car of the kind which is simpler in construccan be rotated, whereby the bottom plate3 55 tion and more efficient in operation than simiwill be displaced towards one or the other lar cars hitherto designed. side and will be depressed on the side, to-

In the car according to this invention the Wards which it has been displaced, by the load end walls are fixed on the wheeled frame. acting thereon.

The side walls are pivotally suspended from Pins 12 mounted on the edges of the bottom 60 the end walls so as to be capable of rocking plate adjoining the end walls project through about pivots arranged near their top edges. curved slots 13 provided in these end walls, The bottom is loosely inserted between the and form pivot-s for links 1 1 hinged at 15 end walls and supported solely by a shaft to the bottom ends of the side walls 16, which 15 extending longitudinally of the car and supare suspended from the end walls by means of 65 t d i b ings fix d to o f ing part hinge pins 17 18 are checks provided on the of the end walls.

While in the modification illustrated in the drawings the link rods 14L are arranged outside of the wagon body, they might also be arranged within same and in that case the slots 13 and 19 might be dispensed with- Alternatively these linksmight also be bent"; so as to avoid} the necessity of providing slots 19. In order to 'be able to discharge several wagons of a train of waigons' atz a tiine, the shafts 4 of adjoining wagons may be provided with coupling means, whielrma-y be of-a pneumaticor electric kind so that by displac:
